Northern European Enclosure Dam

The Northern European Enclosure Dam (NEED) is a proposed solution to the problem of rising ocean levels in Northern Europe. It would be a megaproject, involving the construction of two massive dams in the English Channel and the North Sea; the former between France and England, and the latter between Scotland and Norway. The concept was conceived by the oceanographers Sjoerd Groeskamp and Joakim Kjellsson.
